Email to Project Management Software

Hi there,

We use Active Collab for Project Management. They have a feature that allows us to email directly into a Project that we have created using an email that is supplied for the Project.

For some reason this wasn't working, we tested quite a few things but the final thing that tech support at Acive Collab noticed was the Header in the email contained some wording that won't allow the email to go through on there end. They noticed in the email code that soem of those terms are in the email coming from Jot Form - was wondering if we could get them removed or changed so that we can get our forms in the project. I have pasted below what tech support was referencing and the screen shot he supplied which has the term underlined.

As far as I understand, it is not possible to remove the Return-Path header from the messages which are being sent from our mail servers. According to the SMTP standard, the return-path must be supported. Here is a fragment from RFC 5321 which specifies the SMTP protocol:

When the delivery SMTP server makes the "final delivery" of a message, it inserts a return-path line at the beginning of the mail data. This use of return-path is required; mail systems MUST support it.
